ExplorerFrame.dll / Windows 7 x64

I tried yesterday to help a friend of mine, he is using Windows 7 Ultimate x64 When i replaced the ExplorerFrame.dll and 2 more files ( pnidui.dll and SndVolSSO.dll ) the OS didn't startup at all. I use those 3 files for my OS, but i'm running x86. Can you help me,please ? He liked the way i customized my Windows, but i can't help him with those 3 files. How could i make them compatible with x64 ? Any chance ? Thanks in advance.

Firstly, why would you have used a 32 bit dll on his machine? And no you can't really make a 32 bit dll compatible with the 64 bit one required on his machine. Did you create a backup of his dll's at all?...
